[API] create controller for endpoints needed for adding data from DEI

[jeff-knurek]

Problem

The DEI needs to leverage the API as connection to the database. In order to save a DSL from the spreadsheet https://docs.google.com/spreadsheets/d/1mVyQxxLxAF3E1dw870WHXTOLgYzmumojvzIekpgvLV0/edit#gid=629188932 controllers for

• /DSL
• /Category
• /DataPoint

need to be created

	DateUpdated 
​
​
Category
	_id : ObjectId
	CategoryRefID : string
	DSL._id : ObjectId

	Name : string
	Description : string
	IconID : string
	Tags : []string
	Order : number

	DateCreated 
	DateUpdated 
	
​
DataPoint
	_id : ObjectId
	DataPointRefID : string
	Category._id : ObjectId
	NameShort : string
	Name : string
	Description : string

	Tags : []string
	Order : number
	DateCreated 
	DateUpdated 
​
​
DataSetEntry
	_id : ObjectId
	Funnel/Type/Source : enum or Funnel
	Status : enum or Status
